Trying to look for the strongest dual-back cannon (like the one bolt is equiping)? Well, it's in the mission where you have to defend enemies in the mined grava desert. When you begin, turn east (fast as you can!) then destroy the obstacle and a white pole should be there. Grab it and beat the mission. It's really useful when you play one of the last missions, Eliminate AC intruder.
